We are currently enrolled in this multicentre study to investigate the possible influence of the genetic background in the disease pathogenesis, and to try to establish links between genetic variations and different clinical and biological patterns. The research is led by Prof. Javier Martín from the "Instituto López-Neyra" of Parasitology, CSIC (Granada). We contribute by sending samples from our cohort of patients along with the clinical data, and reviewing the results. It is supported by a SAS grant.

This is a multicentre study supported by the Systemic Autoimmune Diseases Group (GEAS) from the Spanish Internal Medicine Society (SEMI). The aim of the study is to describe the different clinical forms of presentation of these diseases, the response to the conventional treatment of the different subtypes of vasculitides, and the prognostic factors and survival in our country. This study includes 17 Hospitals from Spain with a cohort of 300 patients. We are the study coordinator Centre.
